Abstract

A nuclear magnetic resonance (NMR) probe (16) with a 1H channel comprising: a primary circuit with a coupling coil (L2) which is galvanically connected to an impedance port (5) for feeding RF-pluses with a frequency corresponding to 1H nuclei into the 1H channel, and a secondary circuit with a sample coil (L1) for applying and receiving RF pulses to/from a sample and at least one tuning element (6, 7) which is galvanically connected to the sample coil (L1) for tuning a first resonance circuit of the 1H channel, wherein the coupling coil (L2) is inductively coupled to the sample coil (L1) to couple the RF-signals into the sample coil (L1), is characterized in that the coupling coil (L2) is arranged co-centrically and symmetrically to the sample coil (L1). A more efficient inductive coupling can be provided in order to apply a strong RF magnetic field to the sample, especially on the 1H channel without degrading the sensitivity of multi-tuned single coil NMR-probes, in particular in MAS applications.
